A kabiri girder hejuru ya craneni ubwoko bwa crane ifite ibyuma bibiri byikiraro (nanone bita crossbeams) uburyo bwo kuzamura hamwe na trolley bigenda. Igishushanyo gitanga ubushobozi bwo guterura hejuru, gutuza no guhinduka ugereranije na crane-girder imwe. Crane ebyiri-girder ikoreshwa mugutwara imitwaro iremereye hamwe nibisabwa bisaba neza neza ibikoresho.
Ibirangakabiri girder hejuru ya crane:
Uburyo bwo guterura no gukora bwateguwe muburyo butandukanye kugirango harebwe niba buri kintu kigizwe nukuri kandi gihinduranya, hamwe noguhuza kwinshi, gukora neza, kugabanuka kwinshi, no guterana byihuse.
Imiterere iremereye cyane irakomeye, iramba, kandi ifite ubushobozi bunini bwo kwikorera imitwaro, ishobora guhuza n'imikorere mibi.
Uburyo bwo gufata no kuzamura byahujwe byoroshye kugirango bisimburwe vuba.
Imashini yose irahinduka inshuro yihuta kugenzura, hamwe no gutangira neza no gufata feri, umutekano kandi byoroshye gukoresha.
Ibikoresho byo mu rwego rwo hejuru birakoreshwa, hamwe no kubungabunga bike no kuramba kwa serivisi.
Ibitekerezo bya double girder eot crane:
Umwanya: Bitewe nigishushanyo cyarwo, ibyuma bibiri bya eder crane bisaba umwanya uhagaze kuruta icyerekezo kimwe, bityo rero ugomba kwemeza icyumba cyumutwe gihagije.
Kwinjizamo: Gushiraho igituba kabiriikirarocrane irashobora gushiramo ibintu bigoye cyane ugereranije na girder imwe.
Igiciro: Bitewe nigishushanyo cyacyo nibiranga,kabiri girder eot crane igiciroihenze cyane ugereranije na girder ikiraro kimwe.
Gusaba: Reba ibikenewe byihariye bya porogaramu yawe, harimo ubushobozi bwo gutwara ibintu, umwanya, hamwe nibisabwa neza, kugirango umenye niba crane ya girder ebyiri ari amahitamo meza.
Mugihe uteganya kugura akabiri girder hejuru ya crane, ni ngombwa gukorana nu ruganda ruzwi cyangwa rutanga isoko. Kugirango tubone agaciro keza, reka tugereranye ibiciro bibiri bya girder eot crane kubiciro bitandukanye. SEVENCRANE irashobora kugufasha gusuzuma ibyo ukeneye no kuguha crane yujuje ibyifuzo byawe byihariye.
